Bayesian estimation of diagnostic accuracy of fecal smears, fecal PCR and serum ELISA for detecting Mycobacterium avium subsp. paratuberculosis infections in four domestic ruminant species in Saudi Arabia.

Paratuberculosis, a chronic wasting disease affecting domestic and wild ruminants worldwide, is caused by Mycobacterium avium subsp. paratuberculosis (MAP). Various diagnostic tests exist for detecting MAP infection; however, none of them possess perfect accuracy to be qualified as a reference standard test, particularly due to their notably low sensitivity.

Vancomycin-resistant Staphylococcus aureus endangers Egyptian dairy herds.

The emergence of pandrug-resistant (PDR) and extensive drug-resistant (XDR) methicillin-resistant and vancomycin-resistant Staphylococcus aureus (MRSA and VRSA) isolates from bovine milk samples along with biofilm formation ability and harboring various virulence genes complicates the treatment of bovine mastitis and highlights the serious threat to public health. This study investigated for the first time the frequency, antimicrobial resistance profiles, biofilm-forming ability, virulence factors, spa and staphylococcal cassette chromosome mec (SCCmec) types of MRSA and VRSA isolated from clinical and subclinical bovine mastitis in Egypt. A total of 808 milk samples were collected from each quarter of 202 dairy animals, including 31 buffaloes and 171 cattle.

Prevalence and herd-level risk factors associated with Brucella infection in smallholders keeping large ruminants.

Brucellosis is a disease that poses a higher risk of transmission to animals and people who have close interactions with them, such as farmers. Therefore, the present study was designed to determine the seroprevalence of bovine brucellosis and associated risk factors in Kasur, Punjab, Pakistan. One hundred pooled milk samples from 100 smallholder mixed herds of cows and buffaloes with a total study population of 425 animals (277 cattle and 148 buffalos) with a range of up to seven animals in each herd were collected and tested through a milk ring test (MRT).

Risk factors for antimicrobial-resistant in dogs: a systematic review.

Identifying risk factors associated with the carriage of antimicrobial-resistant (AMR) bacteria in dogs is crucial to understanding their epidemiology and for developing and refining targeted control measures. However, relevant data is scattered and conflicting findings have been reported. This systematic review aimed to compile risk factors associated with the carriage of AMR- in dogs worldwide and to identify relevant knowledge gaps for directing future research.
